Do you need a building permit in Shrewsbury, NJ?

Yes. The Borough of Shrewsbury has established its own construction code enforcement agency to enforce the New Jersey Uniform Construction Code inside the borough¹. A construction permit is required for new construction and for structural, plumbing, mechanical or electrical work on existing buildings; ordinary maintenance and routine repair are exceptions⁷. Monmouth County does not issue the permit for work inside Shrewsbury⁷. A new building also cannot be occupied until a certificate of occupancy is issued⁸.

Who issues building permits in Shrewsbury, and how do you reach them?

Building permits are issued by the borough's Construction Office at 419 Sycamore Avenue, which the borough lists with a phone of 732-741-4200 and the email construction@shrewsburyboro.com⁹. Inside Shrewsbury, send questions about building permits there, not to the Monmouth County planning counter. Fees are the borough's own: the plan review fee is 20% of the new construction permit charge, paid at application and not refundable⁶.

Does Shrewsbury have zoning, and what does it mean for RVs, tiny homes and lot size?

Shrewsbury has its own zoning. The borough adopts and administers a zoning ordinance, Chapter 94, Zoning and Land Development, with districts that begin with R-1 single-family residential². The district list also includes R-1A, R-1B, R-2 and several business and industrial zones¹⁰. Minimum lot size, setbacks, lot coverage and building height are district-specific, set in a schedule attached to the zoning chapter²¹¹. We could not confirm those figures, or any rule on RV living, tiny homes or accessory dwellings, so ask the zoning officer before you buy; the R-zone permitted use we saw is a single detached house. The zoning officer and Land Use Board are reachable through Borough Hall¹².

How do septic permits work inside Shrewsbury?

New Jersey law bars a building permit for a new building until the board of health having jurisdiction certifies that the water supply and sewerage facilities comply with state standards³. A septic system must also be inspected by the board of health before it is covered¹³. Which board covers Shrewsbury is not something we could confirm: Monmouth County's Office of Public Health handles septic and well approvals for its member municipalities, not every town¹⁴. Ask Borough Hall, or call the¹⁵. If a public sewer is available, state plumbing rules can require connection when a septic system is no longer suitable¹⁶.

Building a home in Shrewsbury: the steps, in order

1. Ask the zoning officer to confirm the district, permitted use and dimensional limits for your lot¹².
2. Get septic or sewer and water approval from the board of health having jurisdiction³.
3. Apply to the Construction Office; the plan review fee is due at application⁶.
4. Schedule the required inspections with at least 24 hours' notice¹⁷.
5. Obtain the certificate of occupancy before moving in⁸.
6. If you build the home yourself, file the owner's affidavit with the construction official before the certificate is issued⁵.

What stays with Monmouth County, and what to check before you buy

Monmouth County does not zone and does not issue construction permits inside Shrewsbury¹⁸. It does review subdivisions and site plans that touch county roads or drainage¹⁹, although site plans for one- or two-family homes are exempt from that committee's review²⁰. A driveway onto a state highway needs a NJDOT access permit²¹. Monmouth County's typical home value is $787,429²² and its effective property tax rate is 1.8%²³. Rules for land outside the borough are on the Monmouth County page.

Watch-outs

• We could not confirm minimum lot size, setbacks or RV and tiny home rules for Shrewsbury's districts; the zoning officer can give the schedule for your parcel¹².
• Septic and well approvals may not come from the construction office; confirm which board of health covers the borough before you design³.
